TEST FOR CONVERGENCE OR DIVERGENCE THE SUMMATION OF  Un=(7r)to the power r .from r=1 and infinity

calculusfunctions · Answer

Do you mean$$U(n)=\sum_{r =1}^{n}(7r)^{r}$$

anonymous · Answer

exactly the one above

calculusfunctions · Answer

OK so do you know what to do next? Do you know the type of series is represented?

anonymous · Answer

no

calculusfunctions · Answer

First, if you were to translate from the language of Mathematics to English, what does it read? Can you write it in words?

calculusfunctions · Answer

It reads "The sum of seven r raised to the rth power from r equals one to infinity". Right?

calculusfunctions · Answer

$$\sum_{r =1}^{n}(7r)^{r}=\sum_{r =1}^{n}7^{r}r ^{r}$$Agreed or disagreed?
